FILLING-FORK FOR LOOMS. i j

Beit known that I, EDWARD S. STIMPSON, a c1t1zen of the nited States, residing in mentin Filling Forks for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of improved filling-detecting incohmay be bent out of others. Various causes account for the bending but perhaps it occurs most frequently when a shuttle is caught between the fork and the grid. Occasionally the protector mechanism will get out.of order, so that i l' the shuttle is not boxing properly the i'lagger fails to catch in the frog, and the lay may come to front center with the shuttle out of the box. if the shuttle is in the shed is in the path of the fork it is very apt to bend it, and in many cases the fork is not straightened. out properly, or if straightened, it does not take much graze a bar of the grid occasionally, depending upon the variable sidewisc movement of the lay, and then the bend is very hard to detect.

It is Well known by those engaged in the practical operation of looms that With the ordinary form of fillingdork, in \VlIiCl'l the tines separated at their lower ends, a loop or trailing end of filling is very apt to become entangled around one or more of the tines. This objection is obviated. by the fork constructed in accordance with my present invention, as tlnlim-s are connected at their lower ends. I

When the tines of a fork'are not integral with the loop or tail one or more of the tines,

or the tail itself, may become loose, and in fact such looseness is very apt to occur, and manifestly any such looseness tends to interfere with the pro er detecting action of the fork. Such an o by making the tines and tail or loop integral, as will appear hereinafter.

In accordance with my present invention I so construct the fork that the tines are kept in alinement, it is so strengthenedthat it can Withstand without injury a blow ofconsiderable force, and if it is bent'at all all of the jection is obviated herein .tines will be affected, so that there'will be r little trouble in locating the fault. The various novel features of my invention will be fully described in the subjoinedspecification and particularly pointed out in the following claims.

igure 1 is a perspective view of a loom with one embodiment ent invention applied thereto; transverse section on the line 2, Fig. 1, looking toward the left Fig. 3 is a front elevation of the grating or grid; Fig. 4 is an enfillingetector or fork. 4

The lay 1, shuttle race 2 intersected bythe transverse recess 3. for t fork-tines, the shuttle-box 4, (part *shown in Fig. 1) and the fork-slide 5, only the rear end thereof being'shown in Figs. 1 and 2, may be and are all of substantially Well own or usual construction, the nearer side of the fork-slide being broken out in Fig. 2. In the present embodiment of my invention the fork-tines are joined at their lower ends by a transverse bar or connection, giving greatly added strength and stillness thereto and insuring the bending of all of the tines if one is bent. v

The tines 6 are herein shown of sheet metal, connected at their lower ends by a transverse. bar 7, and'herein the tines and bar are stam e'd or died out of a single piece of metal, making a very simple, 'chea and efiicient construction, the 100 -like tai 8 being integral with the tines. he body portion of the fork is preferably made as a casting, having a flat art 9 and a raised, transverse convex portion 10 having a hole 11 for the pivot pin 12, Figs. 1 and 2, by which the fork is pivotally mounted on the slide 5. Between the upper ends of the tines and the tail 8, the connecting metal is bent around of the body of the e passe e of 'the' the portion 10 of the body, as at 13, and seabsent, the rearward turning" of the ends of cured by'rivets or other fastenings 14 to the flat part 9. 1

The upright bars 15 of the grate or grid are turned rearwardly at their ends, at 16, and connected at the extremities of such extensions, an ear 17 on the gridserving to fasten it in lace on the lay.

Re erring to the drawings it will be seen that a clearance is left at 18, Fig. 2, between the lower ends of the grid bars and the bottom of the recess 3, so that the connection 7 can pass into the clearance when the filling is the grid bars permitting the fork tines 6 at such time to pass between the bars.

Herein I have shown the tines as crimped or corrugated, as at 6 in order to hold intact filling at the same oint on the tines at which the tines at the point of engagement, and thetines when tilted cannot be carried over the. g thread.

. It will be manifest that the fork herein shown can be madevery light and sensitive, for by makin the tines of sheet metal their weight is re need, and they stillness and single piece of metal is effected at a single operation, and the bending to fit the body, with the attachment of the sheet metal portion thereto, are sim leand rapid operations.

Having describe my invention, what I claim as new and desire to secure by Letters Patent, is

1. As an article of manufacture, a fillingfork comprising a body portion, a plurality of tines rigidly connected at their lower ends, and a tail, the tail, tines and. rigid connection being integral and secured to the body por tion, said tines being crimped or corru ated. 2. As an article of manufacture, a fillingfork havingtines crimped or corrugated.

3. As an article of nuinufacture, a filling fork comprising a castimetal body, and attached sheet-metal times formed in onepiece and crimped or corrugated.

4. As an article of manufacture, a fillingfork comprising a cast metal body, and attached tines of sheet-metal crimped or corrugated and integrally connected at their lower ends;

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
